Edwinda, sorry about calling you Edward previously. I do know of the plantation you are talking about. I don't know much about it though. My Woodlands Plantation was in southern Adams County, MS close to Wilkinson county and it went through at least 3 name changes.
If you want to know more about your specific plantation and it's history, first I would contact the Historical society of Wilkinson County which is located in Woodville, MS. I believe Centreville also has a historical society, but I'm not sure what their holdings are. You can google both organizations.
Also familysearch has put some county records online for Mississippi. There are tons of tax records there. Check both Wilkinson and Amite county taxes. Wilkinson County has two seats and shares Centreville with Amite County.
One more thing, Wilkinson county is on the border of Louisiana and there were many migrations between Wilkinson Co and all points south including as far as Baton Rouge, LA.
I hope these bits of information help you in your search for the Mulls and any connection with the Woodlands Plantation.
